Silly hide and seek joke

Two boys named Trouble and Shut Up play hide and seek. Shut Up is the seeker.

A policeman comes and asks him "What's your name?"

"Shut Up." he replies.

"Excuse me?!"

"I said,shut up."

"Are you looking for trouble, boy?!" Yells the police.

What does Shut Up say?

"Oh, yeah! But don't tell me where he is, we're supposed to be playing hide and seek!"
